' LOOM-SlHUTTLE.

Specification of Letters Patent.

' Patented Oct. 9, 1917.

Application filed. February 24, 1917. Serial No. 150,782.

To all whom it may concern:

Be i' known that I, NAPOLEON Srmvneo, a

citizen oi the United States, residing at Biddeford, in the county ofYork and State, of Maine, have invented certain new and usefulImprovements in Loom-Shuttles, of which the following is aspecification, reference behad to the accompanying drawings. This,invention relates to improvements in loom shuttles and has'for itsprimary object to provide an improved guide for the weft thread to holdthe same in proper position and prevent the thread from beingaccidentally displaced firom the threading de vice arranged in the weftchamber of the shuttle. I

It is another object of my invention to :provide a guide-eyefor thethread which is of such construction as to efi'ectually obt' iate thebreaking of the thread, thus avoiding the necessity of frequentlystopping the operation of the loom. It is another importantobject of theinvention to provide aguide-eye for shuttles which is applicable to thevarious types of loom shuttles now in general use without necessitatingany material alterations therein and which may also be manufactured:lrom. a single piece'of metal atrelatively small cost.

With the above and other objects in view, my invention consists in thenovel features of construction, combination and arrangement of parts tobe hereinafter more fully described, claimed and illustrated in theaccompanying drawing, in which,

Figure l is a longitudinal section of a well lmown type of loom shuttleshowing my improved gnideeye arranged in operative rei1 n-with thethreading device in the weft chamber;

Fig. 2 is a section taken on the line 2-2 of Fig. 1; and v Fig. 3 is anenlarged perspective view of the eye.

Referring in detail to the drawing, A indicates the shuttle and B thebobbin which is located in the Weft chamber 0. With this chamber, thethreading channel 1) in the nose of the shuttle, communicates. Withinthis "channel, a metal threading device of any that the several partsjust referred to are well known in the art and constitute no part of thepresent invention.

My invention illustrated in detail in'Fig. 3 of the drawing, is adaptedto be arranged at the inner end of the threadin channel D and betweenthe side walls 0? the metal threading device E. The eye is formed from ametal plate 5 which isstamped out or cut to provide the substantiallycircular opening 6 therein with which the lower, relatively narrow endof an entrance throat 7 communicates at one side of said opening. Oneedge of this entrance threat is obliquely inclincd, asshown at 8, andfrom the lower end of this inclined edge an integral part of the metalplate projects and is bent or in clined laterally from the plane of theplate, as shown at 9. The end of this arm or pro jection is formed witha coil 10 therein, the center of which coincides with the center of theopening 6 in the plate 5. The opposite edges of the plate 5 are notchedor recessed, as shown at 11, to receive retainin ,lugs or projections onthe side Walls of th threading device E, whereby the eye plate is heldin position against vertical or lateral shifting movement.

The thread or filling is drawn from the bobbin through the channel D andthe threading device arranged therein in the usual manner, the threadbeing inserted downwardly between the retaining wings or flanges of thethreading device and directcd by the inclined edge 8 of the eye plateinto the opening 6 thereof. The thread is again brought upwardly againstthe edge of this opening and into contact with the laterally bent orinclined extension 9 which directs the thread into the eye 10. Thethread is thus supported by this eye and is freely movable therethroughas it is withdrawn from the bobbin in the operation of the machine. Byproviding the supporting or guide eye for the thread of the constructiondescribed, the tangling or breaking of the thread in the operation ofthe loom is prevented and the thread is at all times properly supportedfor free movement through the threading device and the side eye in thenose of the shuttle. It is unnecessary to make any changes whatever inthe mounting or arrangement of the bobbin or the construction of thelatter in order that the present invention may be adapted to the commonconstruction of loom shuttles.

From the foregoing description, taken in connection with theaccompanying drawing, the construction, manner of operation and severaladvantages. of the device will be clearly and fully understood. 'Thethread eye being formed from a single metal plate may obviously bemanufactured at small cost and is also very durable in practical use.The eye may be readily arranged in position with relation to thethreading device and may be usedin connection with various constructionsof such threading devices without necessitating any material alterationstherein. It will, of course, be understood that the eye can be made invarious sizes as may be required in accordance with the particular. typeor construction of the shuttle. Therefore, while I have shown anddescribed the preferred form and arrangement of the several parts of thedevice, the same is susceptible of considerable modification therein andI reserve the privilege of adopting all such legitimate changes as maybe fairly embodied within the sprit and scope of the invention asclaimed.

Having thus fully described my invention, what I desire to claim andsecure by Letters Patent is:

1. A throat guide for 100m shuttles consisting of a fiat metal platehaving an opening therein and an entrance throat communicating with saidopening, said plate having an extension formed integrally therewith atone side of the entrance throat,

said extension being of. circular form in.

cross-section and bent to provide a single thread receiving coil thereinterminating on an imaginary line extending through the opening in spacedrelation to the edge thereof.

2. A throat guide for loom shuttles consisting of a flat metal platehaving an opening therein and an entrance throat communicating with saidopening, an extension integrally formed with the plate at one side ofsaid entrance throat and sharply ofiset in a lateral direction from oneside of the plate, said extension being formed into a single threadreceiving coil disposed in substantially parallel relation to the planeof the plate.

3. A throat guide for loom shuttles consisting of a fiat metal platehaving an opening therein and an entrance throat communicatingwith saidopening, said plate being further provided with a laterally ofiset,thread receiving eye disposed in spaced relation to said opening and insubstantially parallel relation to the plane of the plate.

4. As an improved article of manufacture, a throat guide for loomshuttles consisting of a fiat metal plate having an opening therein andan entrance throat communicating with said opening, one edge of theentrance throat being obliquely inclined, and an extension integrallyermed with the plate and projecting laterally from the inner end of saidinclined edge of the throat, said extension being formed into a singlethread receiving eye disposed in spaced relation to said opening.

In testimony whereof I hereunto aifix my signature in the presence oftwo witnesses.
